Abstract:

A computer model for simulation of smoke movement through air conditioning systems is described. A brief overview of air conditioning systems is presented. The methods of calculation of mass flow, smoke transport, fan flow and duct and fitting resistances are presented along with a general description of the program logic. Eventually a computer software will be available, but it is still in the developmental stage as this report goes to press. (Parts of this have been incorporated into CFAST; contact Dr. W. W. Jones for more information.)
